A Roman arch bridge from 203 CE that survived the 2023 earthquake untouched, still carrying traffic 1,800 years later.
Built 203-204 CE by soldiers of the Roman Sixteenth Legion after Septimius Severus's Parthian campaign, funded by 'the four towns of Commagene.' Four dedicatory pillars originally carried statues of Severus, his wife Julia Domna, and sons Caracalla and Geta - only the Geta pillar's statue is missing, likely removed after his damnatio memoriae.

Look for: The single unadorned arch, 120m long and 34m in span; the four pillars, one now empty where Geta's statue once stood.
